Electronic device housing

1. A housing of an electronic device, comprising: a bottom cover comprising at least one first sidewall; a front panel detachably secured to the bottom cover; and a locking portion perpendicularly set on the at least one first sidewall; wherein the front panel comprises a fixing portion defining a through hole for receiving the locking portion and a blocking portion adjacent to and spaced from the fixing portion; the fixing portion and the blocking portion abut opposite surface of the at least one first sidewall for preventing the at least one first sidewall from leaving a gap between the first sidewall and the locking portion; and the blocking portion perpendicularly extended from the inner surface of the front panel; the length of the blocking portion is equal to the distance between the front panel and an edge of the through hole adjacent to the front panel.

2. The housing of claim 1 , wherein the fixing portion comprises a first plate and a second plate; the first plate is parallel with the at least one first sidewall; the second plate perpendicular bents from one edge of the first plate and connects with the inner surface of the front panel; the through hole is disposed on the first plate.

3. The housing of claim 2 , wherein the blocking portion is parallel with the second plate and perpendicular to the first plate.

4. The housing of claim 1 , wherein the locking portion is set on the outer surface of the at least one first sidewall.

5. The housing of claim 1 , wherein the locking portion is a hollow right-angled triangular prism and made of elastic material.

6. The housing of claim 5 , wherein edges of the locking portion opposite to a second sidewall perpendicularly extends from the first sidewall to form an abutting portion for securing the front panel.

7. An electronic device, comprising: a housing with a bottom cover comprising at least one first sidewall; a front panel detachably secured to the bottom cover; and a locking portion perpendicularly set on the at least one first sidewall; wherein the front panel comprises a fixing portion defining a through hole for receiving the locking portion and a blocking portion adjacent to and spaced from the fixing portion; the fixing portion and the blocking portion abut opposite surface of the locking portion for preventing the at least one first sidewall moving in a direction parallel with the front panel; and the fixing portion comprises a first plate and a second plate; the first plate is parallel with the at least one first sidewall; the second plate perpendicular bents from one edge of the first plate and connects with the inner surface of the front panel; the through hole is disposed on the first plate.

8. The electronic device of claim 7 , wherein the blocking portion perpendicularly extends from the inner surface of the front panel; the length of the blocking portion is equal to the distance between the front panel and an edge of the through hole adjacent to the front panel.

9. The electronic device of claim 8 , wherein the blocking portion is parallel with the second plate and perpendicular to the first plate.

10. The electronic device of claim 7 , wherein the locking portion is set on the outer surface of the at least one first sidewall.

11. The electronic device of claim 7 , wherein the locking portion is a hollow right-angled triangular prism and made of elastic material.

12. The electronic device of claim 11 , wherein edges of the locking portion opposite to the second sidewall perpendicularly extends from the first sidewall to form an abutting portion for securing the front panel.
